Answer:
Digital logic circuits made of cascaded flip flops.
The different types of Bit Shift Registers are; Serial-In Serial-Out, Parallel-In Parallel-Out, Serial-In Parallel-Out, Parallel-In Serial-Out.
Shift registers can be used as converters to translate data, as delay circuits or counters.
Explanation:
Shift Registers are digital logic circuits made of cascaded flip flops. Their main function is to shift their contents (bits) to the right or to the left one bit at a time. Bit Shift Registers can process data either parallelly or serially. So the different types of Bit Shift Registers are;
- Serial-In Serial-Out
- Parallel-In Parallel-Out
- Serial-In Parallel-Out
- Parallel-In Serial-Out
Because of their ability to convert data from parallel to serial, shift registers can be used as converters to translate data. Some of their other applications are also delay circuits or counters, storing and manipulating data etc.
I hope this answer helps.
Answer: So have you done assignment 5? and have you read back the previous one?
Answer:
In cell A3 we type
=Right(A2,5)
Explanation:
The Right function in the Microsoft excel is placing the character or the string into the right position .Following are the syntax to using the right function in the excel sheet
=Right(cell name,num _of_character )
- cell name-In this we have to specify the cell name
- num_of_character -In this we have to specify the number of character we want the right of the cell name .
From the given question We have putting the string in the cell A2 and we have used the function in the cell A3 i.e
=Right(A2,5)
Answer: The answer to the question is as follows:
Minimum BW= n*Bc + (n-1) Bg
Explanation:
FDM is a multiplexing technique that takes several baseband signals of n Khz wide (let's assume that all have the same bandwidth), and translates them in frequency so they can be transmitted together, at a higher frequency.
If we assume no guard bands between the different signals, the mimum bandwidth needed would be n times the bandwidth of a single signal.
In order to avoid crosstalk between signals, as the communication channel is not perfect, it usually leaves some room between any 2 signals, which it is called a band guard, and because there is a band guard for any 2 contiguous signals in the spectrum, the total number of bandguards (Bg) will be equal to (n-1) signals, so the total bandwidth to be used will be as follows:
BW needed: n*Bc + (n-1) Bg.
